> This particular virus being novel and so contagious means there's really no hope of stopping its spread, right?
How do you explain the infection rates in Japan, Korea, or Germany, which were never high and remain very low. Or France, Italy or Spain, which were VERY high and have since been well contained?
Yes, we can keep this under control. It takes discipline and care, and some amount of sacrifice. But it can be done. We're just doing it badly.
But no, not "everyone" needs to literally stay home forever. Wear a mask. Stay 2m from other human beings. Stay outside. In particular avoid "static" indoor environments like restaurants (or bars, cruise ships, theaters, etc...) which have been the source of the bulk of local outbreaks. Work from home as much as possible.
Don't write it off as impossible to contain when it's not. We can do much better, and there are tens (or maybe hundreds) of thousands of lives that can be preserved still.
